Caution on degrading trail type:

Joining an easy shaded mid-level concrete path (1Km, coming from Tsing Shan Monastery for CLP pylon maintenance) is a bare mud trail (400m, southbound downhill to Sun Tuen Mun Center).

Unprepared leisure hikers may have to turn back here.

Caution on Route Selection.
1) RHS = Peak ascent 青山登顶
2) LHS = Mid hill descent 横山中電維修徑

There is a metal sign plate "青山徑" but confusingly sited in the middle of the junction and lacking any direction arrow. Often folks heading for the peak (right turn) inadvertently picked the straight-on path (left side).
